    摘要： An object is to provide a novel material having a bipolar property. Another object is to provide an oxadiazole derivative having a wide band gap. Another object is to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. The present invention provides an oxadiazole derivative represented by General Formula (1). In the formula, Ar1 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring, A represents a substituted or unsubstituted phenylene group, R11 to R15 and R21 to R25 are independently any of hydrogen, an alkyl group having 1 to 4 carbon atoms, an aryl group having 6 to 10 carbon atoms in a ring, and a substituted or unsubstituted 9H-carbazol-9-yl group.

    摘要： A novel carbazole compound that can be used for a transport layer, a host material, or a light-emitting material in a light-emitting element. In the carbazole compound, two carbazole skeletons each include carbazole, the 3-position of which is bonded to the 4-position of a dibenzofuran skeleton or a dibenzothiophene skeleton and these two carbazole skeletons are linked via benzene or biphenyl. The carbazole compound has an excellent carrier-transport property and a wide energy gap and can be suitably used for a material in a light-emitting element or for an organic semiconductor material.
